Fainelli, Federico, Gottschlich, Günter & Orsenigo, Simone, 2024, Nomenclatural notes on some names in the Hieracium tenuiflorum group (Asteraceae) of the Alps, Phytotaxa 645 (2), pp. 131-148 : 140

22. Hieracium murorum subsp. pseudomerianum P.Rossi & Zahn in Zahn (1934: 482)

Ind. loc.:—“Comer See z. B. Ponte S. Pietro im Val Sassina und zwischen Genico und Croce di Brentalon; Menaggio”.

Type:—[ ITALY, Lombardy, Prov. LC] “Sulle rupi umide lungo il lato sin. della Pioverna da Prato S. Pietro a Cortenova, poco sopra il letto del torrente, 24 Aug 1920, P. Rossi ” (lectotype, designated here: PAV barcode PAV-LOM014260 ; isolectotype: PAV barcode PAV-LOM014969 ) ( Fig. 3 ) .

Remarks:— Two specimens in PAV were collected on the same date by Pietro Rossi in Prato San Pietro. In the protologue Zahn indicated the wrong locality Ponte San Pietro in Val Sassina. The correct name is Prato San Pietro as stated on the label of Pietro Rossi. One of the two specimens (PAV-LOM014969) has damaged capitula that are enclosed in a paper bag. The second one (PAV-LOM014260) is a well-preserved specimen that bears two different labels handwritten by Zahn. On the first label there is only the new combination [“ Hieracium murorum L. (grex H. tenuiflorum Zahn H. d. Schweiz p 221) n. ssp. pseudo-merianum Rossi et Zahn 1923 ”]. On the second label there is a long diagnosis handwritten by Zahn, describing the new subspecies in detail ( Fig. 3 ). This specimen agrees perfectly with the protologue, and therefore the specimen is designated here as a lectotype. The second specimen (PAV-LOM014969) can be considered an isolectotype.

Current name:— Hieracium tenuiflorum subsp. pseudomerianum (P.Rossi & Zahn) Gottschl. in Raab-Straube & Raus (2013: 157).
